ok, here are some pics of my tires, they seem to be wearing unevenly in a weird way. i just want to see if anyone else has seen this before. my jeep in an 08 2dr with 35in pro comps. i am running 35 psi. i have emailed pro comp but they arent much help at all. my first set i had before this one had no issues at all and i have not added anything to the jeep since then. btw i have had this set on for less than a year. i think next go around i will try something else! here are the pics

 

That's called cupping, did u ever rotate your tired......

 

every 3000 miles with oil change

 

I rotate mine every three and also does this. Mine only seems to do this on driver side front. Mine are km2

 

Probably depends on the kind of tires

 

35 PSI seems a bit to much and that might be your problem. I have mud grapplers and I usually run 28 PSI in them. I recently went to 33 PSI since I've been driving alot of highway to see if I would get a little better gas milage and mine have started to cup. But I may be wrong on this.

 

Every tire is doing this?

 

Every time I change my oil, I rotate for that reason. Plus they will last a lot longer!

 

Can also be caused by a bad shock absorber. When bad it will look like diagonal bands all across the tire. Tires will feel squirely when it is bad; can be dangerous to drive because of poor tread contact with road. My DC FC IIs did that.

 

ive got 35x12.50x18 pro comp xtreme mud terrain and i rotate every 5000 and i run 50 psi. they are about 20,000 miles and are wearing beautifully. i might try running more air
